Description

Technical Field

[0001] The invention relates to the technical field of metal workpiece cooling and forming, in particular to a discrete continuous chilling and solidification device. Background Art

[0002] Aluminum alloy components are widely used in various fields, including automobiles, engines, aerospace, and new energy. With the maturity of technology and the improvement of product performance, the service life of mainframes in various fields has been significantly extended, which places higher demands on the material properties of aluminum alloy components. The addition of intermetallic compound aluminum master alloys to aluminum alloy casting and melting can improve the processability and material properties of aluminum alloys. Intermetallic compound aluminum master alloys in the liquid state promote nucleation and refine the solidification structure. For aluminum master alloys containing intermetallic compounds, the chilling conditions will cause the intermetallic compounds to be more finely distributed, which will enhance the intermetallic compound nucleation effect, improve the material processability and material performance, and at the same time, require high production efficiency, which requires suitable equipment to produce aluminum master alloys.

[0003] Existing continuous chill forming equipment for aluminum master alloys generally includes a cooling crystallization wheel with a flexible steel belt on the outside of the cooling crystallization wheel. The flexible steel belt squeezes the cooling crystallization wheel to form an aluminum master alloy cooling and forming space between the flexible steel belt and the outer surface of the cooling crystallization wheel. After the aluminum master alloy casting liquid enters the cooling and forming space, it is cooled and formed, and then unloaded from the cooling crystallization wheel to obtain an aluminum master alloy strip. If the strip is not cut, it can be extended indefinitely, which is inconvenient to store, transport and use. Usually, the aluminum master alloy strip is cut into a certain length by a cutting machine before use, which increases the processing steps and production costs. Summary of the Invention

DETAILED DESCRIPTION

[0024] Reference Figure 1-7, a discrete continuous chilling solidification device, including a support frame, which can adopt the structure shown in the figure, and can have a bottom plate 51, a left side plate 52 and a right side plate 53. Of course, support frames with other structures can also be adopted. Its purpose is to support the corresponding components on the device. Support frames with other structures are not described here. In the structure of the support frame of this embodiment, the two sides of the bottom plate 51 are fixedly installed with opposite left and right sides 53. The shapes of the left and right sides 52 and 53 are both inclined at the bottom and vertical at the top. The left and right sides 52 and 53 are symmetrically arranged, and the distance between the inclined sections of the left and right sides 53 gradually decreases from bottom to top. The left and right plates 52 and 53 are both provided with rotating bearings 55 on their inclined sections. The axial direction of the rotating bearings 55 is perpendicular to the plate surface of the above-mentioned side plates (referring to the left and right plates 52 and 53). The left rotating shaft 21 and the right rotating shaft 22 are installed in the rotating bearings 55. The left rotating shaft 21 and the right rotating shaft 22 are both inclined downward from the outside to the inside, so that the axial directions of the left rotating shaft 21 and the right rotating shaft 22 are at a set angle. The downward inclination from the outside to the inside means that the height of the inner end of the shaft is lower than the height of the outer end of the shaft, so that the angle between the axes of the two shafts is an obtuse angle, so that when the connecting arm driven by the shaft rotates to the top, the distance between the outward-extending ends of the two corresponding connecting arms becomes smaller. When the two corresponding connecting arms rotate to the bottom, the distance between the outward-extending ends of the two corresponding connecting arms is the largest. In other words, the two corresponding When the connecting arms rotate with the left rotating shaft 21 and the right rotating shaft 22 respectively, the distance between the outwardly extending ends of the two corresponding connecting arms gradually decreases from bottom to top, and it is easier to clamp the mold when the guiding and clamping mechanisms on the upper parts of the left side plate 52 and the right side plate 53 guide the left mold and the right mold; the left rotating shaft 21 and the right rotating shaft 22 are connected by a coupling 23, so that the left rotating shaft 21 and the right rotating shaft 22 axially cross and rotate synchronously, and a motor fixing frame 54 is fixedly mounted on the outer side of the inclined section of the left side plate 52, and a variable frequency speed regulation motor 11 is fixedly mounted on the motor fixing frame 54, and a driving gear 12 is fixedly mounted on the output end of the variable frequency speed regulation motor 11, and a driven gear 13 is fixedly mounted on the outer end of the left rotating shaft 21, and the driving gear 12 and the driven gear 13 are meshed and rotated, so that the variable frequency speed regulation motor 11 drives the left rotating shaft 21 and the right rotating shaft 22 to rotate synchronously.

[0025] A fixed sleeve 24 is provided on the left rotating shaft 21 and the right rotating shaft 22 respectively. The sleeve 24 is located between the left plate 52 and the right plate 53. The outer circumference of the two sleeves 24 is provided with a mounting groove 241. A circular spring plate 25 is fixedly installed in the mounting groove 241. The spring plate 25 rotates with the left rotating shaft 21 and the right rotating shaft 22. The spring plate 25 is arranged along the radial direction of the left rotating shaft 21 and the right rotating shaft 22. The area of ​​the spring plate 25 away from the sleeve 24 is evenly distributed with multiple triangular cutouts. Area 251 forms a central portion of multiple spring plates 252 connected to the spring plate 25 and extending outward. The combination of the spring plate 25 and the sleeve 24 mounted on the left rotating shaft 21 is the left disc, and the combination of the spring plate 25 and the sleeve 24 mounted on the right rotating shaft 22 is the right disc. The spring plates 252 serve as connecting arms. The spring plates 252 on the left disc correspond to the spring plates 252 on the right disc. The spring plates 25 can bend and deform when subjected to external force and return to their original positions when the external force is removed. Of course, other embodiments can also be achieved by employing a structure where the left and right plates 52, 53 are not tilted. For example, the left and right plates 52, 53 can be vertically positioned with inclined holes defined in each. Another example is when the left and right rotating shafts 21, 22 are horizontal. By increasing the pressure of the guiding and clamping mechanism, the spring plates 252 (connecting arms) can be sufficiently deformed, allowing the left and right molds to be clamped. The outer edges of the multiple spring plates 252 on the left disc are fixedly connected to the left mold. Figure 2 The multiple left molds form a ring when they are freely expanded, and the outer edges of the multiple spring pieces 252 on the right disk are fixedly connected to the right mold. Figure 4 When multiple right molds are freely expanded, a ring is formed. The left mold and the right mold can be closed one by one to form a mold cavity 37. The left mold, the left disk, the left rotating shaft 21 and the connecting parts constitute the left rotating wheel assembly. The right mold, the right disk, the right rotating shaft 22 and the connecting parts constitute the right rotating wheel assembly. When the variable frequency speed regulation motor 11 drives the left rotating shaft 21 and the right rotating shaft 22 to rotate, the left mold and the right mold rotate up and down synchronously.

[0026] like Figure 2 、 3As shown in Figure 6, the left mold includes a left mold body 31, a left mold core 33 and a left template 35. The cross-section of the left mold body 31 is "L"-shaped and the side is fan-shaped. An axial groove 312 is provided on the bottom edge of the left mold body 31, and a radial groove 313 is provided on the inner side wall of the left mold body 31. The left template 35 is fixed on the axial groove 312 and the radial groove 313, so that the left template 35 is fixed to the inside of the left mold body 31 (the inside refers to the part surrounded by the two sides of the L-shape). The left template 35 divides the left mold body 31 into a large area and a small area. The right side of the left template 35 is flush with the right end face of the left mold body 31 (that is, the side of the left template 35 not connected to the left mold body 31 is flush with the left mold body 31 is flush with the end face of the left template 35), the radial outer end of the left template 35 is pointed, which is convenient for diverting the casting liquid during casting. The fan-shaped left mold core 33 is installed in the space formed by the large area of ​​the left mold body 31 and the small area of ​​the adjacent left mold body 31. The left mold core 33 is fixed on the left mold body 31 where the large area is located, which is conducive to firmly fixing the left mold core 33, while the two adjacent left mold bodies 31 can be dispersed. The axial width of the left mold core 33 is smaller than the axial width of the bottom edge of the left mold body 31, so as to form a mold cavity 37 when the mold is closed; a left circumferential groove 311 is provided under the bottom edge of the left mold body 31, and the outer edge of the spring sheet 252 corresponding to the left mold is fixed in the left circumferential groove 311.

[0027] like Figure 4 、 5As shown, the right mold includes a right mold body 32 and a right mold core 34. The cross-section of the right mold body 32 is a mirror image of the left mold body 31 in an inverted "L" shape, and the side surface is fan-shaped. The fan-shaped right mold core 34 is fixed inside the right mold body 32 (the inside refers to the part surrounded by the two sides of the inverted L shape). One end face of the right mold core 34 is flush with one fan-shaped side of the right mold body 32 (that is, one end face of the right mold core is flush with one end of the right mold body). A distance equal to the thickness of the left mold plate 35 is left between the other end face of the right mold core 34 and the other fan-shaped side of the right mold body 32, so that a cavity 36 with the same thickness as the left mold plate 35 is formed between two adjacent right mold cores 34. The axial width of the right mold core 34 is greater than the axial width of the bottom edge of the right mold body 32; a right circumferential groove 321 is provided below the bottom edge of the right mold body 32, and a spring piece 252 corresponding to the right mold is fixed in the right circumferential groove 321. Due to the axial formation of a certain angle between the left rotating shaft 21 and the right rotating shaft 22 and the synchronous rotation and the guidance of the guide rail 56, when the left mold and the right mold rotate to the upper side, the left mold body 31 and the right mold body 32 move closer to the middle, and the spring sheet 252 is deformed accordingly. The left mold body 31 and the right mold body 32 exert external force on each other under the action of the spring sheet 252 and are pressed together to close the mold. The bottom edges of the left mold body 31 and the right mold body 32 are docked, the right side of the left template 35 is inserted into the cavity 36, and the left side of the right mold core 34 is pressed on the bottom edge of the left mold body 31. The left mold core 33, the right mold core 34, the bottom edge of the left mold body 31, and the two adjacent left templates 35 form a long strip of mold cavity 37. The mold cavity 37 opens upward and outward, and the rest of the surface is sealed. When the casting liquid is poured in, it does not flow out of the mold cavity 37. Figure 7 As shown, the left mold and the right mold form a plurality of mold cavities 37 that are continuous and spaced apart from each other.

[0028] A left water channel 211 and a right water channel 221 are respectively provided in the inner axial direction of the left rotating shaft 21 and the right rotating shaft 22. The left water channel 211 and the right water channel 221 are not directly connected.

The outer sides of all flexible water pipes 45 are surrounded by semi-flexible annular plastic rings 46 to bundle the flexible water pipes 45 circumferentially.

[0029] On the upper vertical sections of the left and right panels 52 and 53 are opposite, arc-shaped guide rails 56. Bevels 561 are located at each end of the guide rails 56. The distance between the two guide rails 56 in the section with the bevels 561 is greater to facilitate gradual alignment, closing, and separation of the left and right molds. A fine-tuning device 57 is provided on the upper vertical section of the right panel 53 for adjusting the guide rails 56 mounted on the right panel 53.

[0030] It should be noted that the terms "left" and "right" are used for ease of illustration in the accompanying drawings. If the terms "left" and "right" are reversed when viewed from the other side of the device, they do not limit the scope of protection of the present invention. The axial, radial, and circumferential directions are defined by the left and right rotating shafts 21 and 22. The device of the present invention can also be used for the chilling and solidification of other molten metals, not just aluminum master alloys.

[0031] Working principle and process: After the equipment is assembled, the universal sealing joint 41 of the left water channel 211 is connected to the cooling water inlet pipe, and the universal sealing joint 41 of the right water channel 221 is connected to the cooling water outlet pipe (or vice versa). The cooling water enters from the left water channel 211, passes through the left radial hole 212, the annular channel 242, the water pipe joint 42, the elastic water pipe 43, and the cooling pipe 44, enters the left cooling hole 331, and then flows out from the side water port 442 through the water gap between the left cooling hole 331 and the cooling pipe 44, and then flows out through the flexible water port 442. The elastic water pipe 45 and the side water outlet 442 of the cooling pipe 44 of the right mold core 34 enter the right cooling hole 341, then enter the cooling pipe 44 through the water gap in the right cooling hole 341, flow out from the straight water outlet 441 of the cooling pipe 44, pass through the elastic water pipe 43, the water pipe joint 42, the annular channel 242, the right radial hole 222, enter the right water channel 221, and finally be discharged from the right water channel 221. The above cooling system cools the left mold and the right mold, and then performs chilling forming on the aluminum intermediate alloy casting liquid in the mold cavity 37. Start the variable frequency speed regulating motor 11, which drives the left rotating shaft 21 and the right rotating shaft 22 to rotate synchronously, and the left mold and the right mold rotate up and down accordingly. When the left mold and the right mold rotate upward to the rear area, the corresponding left mold and the right mold begin to contact the inclined surface 561 of the guide rail 56, and the spring sheet 252 supporting the left mold and the right mold begins to deform. The left mold and the right mold move closer to the middle to close the mold. The right side of the left mold plate 35 is inserted into the cavity 36, and the left side of the right mold core 34 is pressed on the bottom edge of the left mold body 31. The bottom edges of the left mold body 31 and the right mold body 32 are close to each other. The left mold core 33, the right mold core 34, the bottom edge of the left mold body 31, and the two adjacent left mold plates 35 surround to form a mold cavity 37 opening upward and outward. The mold cavity 37 continues to rotate upward. At this time, the aluminum intermediate alloy casting liquid is poured into the mold cavity 37 through the feed port 581 and is excited and solidified in the mold cavity 37. When the mold cavity 37 rotates downward, it contacts the inclined surface 561 at the other end of the guide rail 56. Under the elastic force of the spring sheet 252, the left and right molds begin to separate. When the left and right molds are separated from the guide rail 56, the spring sheet 252 returns to its original position under the elastic force, and the left and right molds disperse, leaving the cooled and formed workpiece 7 on the left mold. When the left mold rotates to the position of the unloading device 61, the unloading rod 611 rotates rapidly toward the workpiece 7, and the sharp corner 612 at the outer end of the unloading rod 611 hits the workpiece 7, unloading the workpiece 7. The workpiece 7 falls onto the conveyor belt 62 and is transported to the storage box. The two nozzles 631 of the air-blowing spray device 63 respectively blow air to clean the left and right molds below, and then spray the release agent. By turning the screws of the fine-tuning device 57, the guide rail 56 on the right side plate 53 can be fine-tuned to better fit the left and right molds.

[0032] The left and right molds of the present invention can be closed and automatically dispersed during the process of rotating up and down.
